We bring together industry, academia and governments to tackle the toughest challenges in vertical flight. Since 1943, we have led technology, safety, advocacy and other initiatives, and have been the primary forum for interchange of information on vertical flight technology.

On July 11, 2013, AHS International and Sikorsky Aircraft presented the $250,000 AHS Sikorsky Prize to Toronto, Ontario-based AeroVelo for flying the first human powered helicopter to meet technical requirements set by AHS more than a third of a century earlier, in 1980.

The winners of the AHS Igor I. Sikorsky Human Powered Helicopter Competition recount their quest to achieve what many considered an impossible goal in vertical flight design.
